  • With our latest release cycle we faced a problem that impacted extremely load intensive long running (multi-day) tests. The symptom was a slow but steady increase in Resident Set Size (RSS) that impacted both our Transaction Engines (TEs) and Storage Managers (SMs). On large machines unless you're looking at "ps" stats you wouldn't notice it, but on typical cloud hardware the OOM killer would take out the NuoDB processes.

    Since our system is

    Database replication is simple, right? You pick the tables to replicate, copy them and then apply new transactions to them (from a log file) to keep them up-to-date.

    Actually, it’s not so simple. In fact most databases don’t do it well at all. We need to distinguish between data copying and sophisticated replication, because copying actually is simple.

    But why would anyone want to replicate data? I think there are three reasons:

  • We will soon be releasing NuoDB 2.0.4 and this release will include support for the latest ADO.NET provider. As the ADO.NET world evolves, especially the Entity Framework (EF), we here at NuoDB are not standing by but are moving the driver forward as well.

    We already have very good support for the standard ADO.NET interface and also Entity Framework 4 and 5 in the current version of the product. With 2.0.4 we are adding support for EF 6.x. EF 6 is a major step forward. The Entity Framework team

  • Join NuoDB tomorrow, Tuesday, April 29th at 11 a.m. EST to ask CTO, Seth Proctor, and Software Engineer, Luke Bayas, your questions about the NuoDB Automation Console and No Knobs Administration.

    The session will start by covering how the client side technologies used to implement NuoDB’s Automation Console make a distributed database usable. Luke will then provide color on the REST management API being built, as well as the web toolkits going into the new UI.

  • Introduction

    In order to certify that NuoDB is a fully-featured database product that can be used to power existing enterprise-grade applications, we frequently migrate various pieces of software to run on NuoDB.

    Recently, we did that with Phabricator , which is an open-source, web-based suite of development collaboration tools, including source repository browser, reviews, bug tracker and wiki. Phabricator is written in PHP and its architecture includes a database abstraction layer, even though it previously only ran on MySQL.

  • Hello again, fearless readers. This post will be a continuation of the discussion started here . I will continue to pontificate upon isolation levels as a SQL construct and how to understand them in a distributed MVCC database like NuoDB. NB: this post, like the previous one will use graphical representations of side-by-side timelines. The first column is 'transaction1' which is running at the same isolation level as the three other columns. Each of the remaining columns are demonstrating the behaviors of the three
